Specification of Letters Patent.

Original application filed October 18, 1897, Serial No. 655,652. Dividedand application filed February 16, 1900, Serial No. 5,434. Thiscontinuation application flied April 6, 1910. Serial No. 553,898.

To all whom it m ay concern Be it known that I, CHRISTIAN F. DILG, acitizen of the United States of America, and a resident of New York, inthe county and State of New York, have invented a certain new and usefulBall-Bearing, of which the following is a specification, the same beinga continuation of my application Serial No. 5334., filed February 16,1900, the latter being a division of Serial No. 655,852, October 18,1897.

My invention relates to ball holding devices, and particularly to thatclass of ball bearings wherein a holder is used, having a series of ballbearing points to retain the balls, the latter projecting beyond thedevice, in the inner andouter, and in the upper directions with respectthereto, and it has for its object the provision of an organization ofthe class described, simple in construction, inexpensive to manufacture,and which operates in a smooth, easy and noiseless manner in practicaluse.

, To attain the desired end, this, my invention, consists in theconstruction, arrangement and operation of the parts herein set forth. v

In the drawings which accompany and form a part of this specification,Figure 1 represents a plan view of a ball holder'embodying my inventionFig. 2 is a plan, and Fig. 3, is a front'elevation of my ball retainer,Figs. 4 and 8 are plan views of two ball holding devices constructedaccording to my invention, Figs. 5, 6, 7 and 9 are views in detail ofsome modifiedforms of my ball holding devices embodying my invention,Fig. 10 is a longitudinal section of a portion of a hub with one of myball retaining devices; and Figs. 1], l2 and 13 are respectively viewsof blanks of which the retaining devices shown in Figs. 2, 4 and 8 aremade.

Like letters of reference indicate. like parts in all the views.

I have found it desirable to devise a ball bearing of simpleconstruction, and one that will be reliable and efficient, as well asnoiseless, in practical use, in which the balls are held in their normalpositions by means of a retaining device, and I have, therefore,constructed according 'to my invention, an organization of the kind setforth, embodying the preferred construction of parts and their mutualrelationship, combination, ar-

rangement and organization in a composite body or structure, ashereinafter described.

Referring particularly to the drawings, A denotes my ball holding deviceformed of suitable material such as resilient sheet metal, and shown aslocated in the chamber formed by the inner flanges of the hub A, and thecones of the axle A, of the present embodiment, and comprisingordinarily a practically horizontal and imperforate ring having a seriesof inner and outer disconnected projections or spurs serving as hearingpoints or detents, to retain the balls 13, and consisting, as in Figs. 1to 3, of inner, and also preferably wider, and outer, and practicallyvertical, side flaps or upwardly and circumferentially extendingprojections A A, ordinarily radially opposite each other, and extendingupwardly from the ring, and also preferably tapering eaten sions or topportions or plates A practically parallel with and overhanging the ringA. and having their free ends bent over so that they contact or lieadjacent the tops of the projections opposite to the ones from whichthey extend. Intermediate each pair of inner and outer flaps orprojections, -spaces or recesses A are formed. The spaces or recessesthus formed areso arranged that the balls contained in them are spacedapart, or, in other words, are prevented from contacting with eachother, and thereby the element of friction caused by the adjacentsurfaces of the rotating balls rubbing against each other in oppositedirections is eliminated.

I sometimes construct my ball holding devices in the form of acorrugated ring, as

shown in Figs. 4 to 7. In this instance, the edges of the walls of therecesses A formed between the upper portions A of the ring, arepreferably parallel with each other, and the same extend upward abovethe center line of the balls B; the side walls a of the same, inconnection with the bottom portion of said ring, constituting therecesses AK; which walls a are preferably inclined toward the balls inorder that the upper portions of each recess will be somewhat smallerthan the lower part thereof. My bearing points or detcnts consist, inthis instance, of one-or more vertical prongs, as m in Fig. 5, locatedin the inner and outer portions of the recess A, or lateral prongs, as

a" in Fig. 6, located along the inner and Patented Nov. 1?, 19M.

7 said recesses, may e o outer edges f preterred. however, the parts myring A.

of the side inclined portions 1 of my ring, iorming he lower portions ofcircular form, as A shown in Fig. 7, or they may be rectangular, as 31Figs. 8 and 9, constituting the recesses A, and to the upper portions,as A supplementary lates A, provided with projecting retaining portionsor points a", formed by the same being laterally recessed or concaved,the said top portions being wider at their outer edge than at the inneredge thereof.

Referring to the form of my invention illustrated in Figs. 2 and 3,which for some purposes is the one I prefer, it will be evident that theprojections A, which cooperate with the other parts of the retainer tohold the balls in place, are 01": such relation to the top retainingportions A? as to prevent the seated balls from falling out of theirrecesses in a direction toward the said parts These plain or nonflangedparts A as is clear from an examination of Fl 11, are integral with thebase ring, being attached to one edge there of, and when they are bentup into position to complet the retainer they constitute retainingportions, along one edge of the base ring, and being turned upwardopposits the parts it, they serve to render the relatively at thosepoints as regards the relatively elastic parts A A in the preferred formmy invention, the ball-retaining device consists of a ring-- sir-spedportion or base A constructed with a series of ball-retaining portionsA, (otherwise herein termed standards) rising or springing from one edgeor margin of the base and terminating in tapering extensions ortop-retaining projections A (otherwise herein termed sectorhaped ortapering or inwardly flaring flanges or extensions) which are arrangedat an angle to the parts A and overlie the base. From the edge of theringor base A opposite the ball-retaining parts A extend the "up-turnedballretaining parts of the retainer designated A and which, as alreadystated constitutes a broken wall or rib along the ed 'e of the ring, theinoperative parts of the retainer, located between the parts A being cutaway. T his construction permits the balls to be sprung into the spacesor recesses A formed for receiving and confining them between theadjacent retaining parts ii, 3?, 52. being retained in such recesses bycontact with the rip-turned portions A at the edge e the ring and theoverl ing portions A w the retainer is removed from the ball race orhearing.

It is manifest that some particulars could terially affecting the myinvention, or the various omissions of be made without meessential'features of operation of the remaining parts, and I do not therefore,wish to be limited to the specific structural details of theorganization set forth herein. Obviously, the elements of the structuredescribed may be located at angle to the plane in which they are shown.I, accordingly, use the words horizontal, vertical, and the like, in arelative sense,

In operation, the balls B, are placed in the recesses between each pairof inner and outer bearing points or projections, and top bearingpoints, so that they project beyond the same in the inner and outer andin the upper directions. be balls are thus securely held in place, and,by means of the construction shown, are allowed to move quite a longdistance radially, and they are thus enabled to adjust themselves, incase of any wearing or" the bearing taking place, the side bearingpoints, as stated, preventing the balls from rolling out of theirsockets, in either a vertical, radial or lateral direction, and, sincethe base or the retaining projections or both are elastic, the balls maybe readily snapped in and out of the retainer, at will.

@bviously, my ball retaining device may be advantageously employed inmany kinds of bearings or sockets, and I do not theretore wish to limitmyself to the use or" my device in connection with ball bearings of thekind shown alone.

I onl claim in this application, together with the generic inventiondisclosed in the construction of a device of. the class des r" nod andshown herein, the specific ball retain 1 to 3, as the speer shown inFigs. .L ciiic retainer shown in Figs. 4 to 9 is claimed in a companionapplication.

As it is evident that many changes in the construction and relativearrangement of parts might be resorted to without departing from thespirit and scope of my invention, I would have it understood toat I donot restrict myself to the particular construction and arrangement orparts shown and described, but that such changes and equivalents may besubstituted therefor, and that W hat I claim as my invention, is
